50 Mile Race Information

The 50 mile version of the Butte 100 is a crowd favorite with epic amounts of single track on the Continental Divide Trail, sweeping views of the Highland mountains, and athletic tests such as the notorious Basin Creek climb. Racers will encounter dense wooded areas with buff packed dirt progressing to loose decomposed granite surfaces. The 50 mile course is sometimes referred to as the “South Loop” because the 100-milers begin their race on the heading to the north portion of the course, before chasing down the 50-milers on the South Loop.
